Hey guys,
At the moment, Tablet Pro doesn't even have any way of checking for updates to the desktop components, and updating the store app obviously doesn't update the desktop components. The Desktop components should have the option to self update, or better yet, since the Desktop components are pretty small, your Windows Store app package could simply come with them. That way, when the user attempts to use either of the Desktop components, the component could always first check if the package in the directory of the Windows Store app matches or is older than the current version. If not, then for the first time after updating the Windows Store package, the component could show a notification stating there are updated desktop components, giving the user to update now, so, it automates installation and just shows prompt to sign out after installing both components seamlessly.
That's the way the desktop components should be as they keep getting improved.
